1 ^{- Software sets ADCON. ADON to start AD operation.}
2 - Sampling starts after discharge period.
TSAMP is described in the “dsPIC30F
Family Reference Manual” (DS70046), Section 17.
3 ^{- Convert bit 9.}
4 ^{- Convert bit 8.}
5 ^{- Convert bit 0.}
6 ^{- One TAD for end of conversion.}
7 ^{- Begin conversion of next channel.}
8 ^{- Sample for time specified by SAMC.}
TSAMP is described in Section 20.8
“A/D Acquisition Requirements”.
